FIRST DRAFT
Build the main body of the arc reactor

After completing the rough model, I tested its ability to fit the electronic components. I used SLA printing for the main body and FDM printing for the holder. However, I misjudged the thickness of the SLA print, causing the Neopixel ring to not fit properly. To resolve this, I need to extend the center diameter to 46mm to ensure compatibility.

SECOND DRAFT


After the first failure, I decided to widen the diameters of both the circles and the holders to improve the fit. Additionally, I worked on the main box underneath to neatly organize and collect the wires from the Neopixel rings and I2C sensors for a cleaner assembly.

The assembly works smoothly overall, but I encountered a few design issues. The on/off switch doesn’t align with the hole in the main box, and the box height is insufficient to accommodate the motherboard. Additionally, I overlooked the gesture sensor placement, so I now need to redesign it to fit in a more accessible and visible position.

THIRD DRAFT


Building on the second draft, I adjusted the size of the hole in the main box and repositioned the gesture sensor to a visible spot at the top of the box. The design is now almost complete!
SOLDERING


With all the parts printed, I began the soldering process, carefully wiring each component onto the perf board. Following my circuit diagram, I connected each wire with precision, ensuring all connections were secure and properly aligned. This process brought the entire design to life, transforming individual components into a functional system.
THE GENERAL TEST BEFORE ASSEMBLY



After four hours of printing, the design has come to life, glowing beautifully as shown in the photos. The vibrant blue lighting adds a dynamic, high-tech feel, perfectly capturing the futuristic essence of the project. I’m excited to power it up through the computer to see it in full action.
